IMPROVEMENT 1N HAT-VENTILATORS.

To ALL wHoM 1T MAY ooNoERN:

Be it known that L-lGHARLES HENRY COFFIN, of San Francisco city and county, State of California, have invented a Acertain new and improved Hat-Ventilator; and I do hereby declare the foliowing description and accompanying drawings are suiicient to enable any person skilled in the art or science to which it most nearly appertains to make andiise my said invention without further invention or experiment.

vThe 'nature of my invention is to provide a ventilator for hats, so constructed that it can be opened and vclQSedAtvwilh andeasiljremoyed from a hat that hasheeome worn out or unfashinnable, and attached to a new one, andI composed of such material as not to corrode and discolor the hat in case it is of a light and delicate material. I

To more fully illustrate my invention reference is had to the accompanying drawings and letters marked thereon, in which-f Y Y Figure 1 is a plan.

Figure 2, a side view. Y

Figure 3, a section, taken vertically through the centre.

A is a lthin plate with scalloped edge, composed of any material which will allow of gilding, or plating, or of pure silver, having radial perforations. A notched ange, B, is placed or attached to the lower face of the plate, forming teeth or holders a a, which are bent back upon th'e inside of the top of the hat, thus confining the ventilator in place. A slide, b, is placed upon the lower face of the plate A, operated by a pin, c. This slide or disk is a. counterpart of the perforated plate A, with openings like it, and when closed completely covering the perforations, similar to that of a slide to aregister.

By this means a hat-ventilator is had-which can be opened and closed, answering the purpose of ventilator when opened, and when closed keeping out the dust or rain from the head of the wearer.

I claim, as a new article of manufacture, a hat-ventilator, provided with a slide or valve to close the openings, and a Bange of exible metal teeth for fastening it to the hat.
